Hi,

medm cartisian plot has an option "Plot Mode" to choose from "plot last
npts" and "plot n pts & stop". This number is specified by the other
option "Count Num or Channel" in "Resource Palette".
It used be OK to use a number in this option but it does not work in
recent versions. If you specifies Channel name in this options, it works.

I studied medm3_1_3 and apply modification shown in the attached file.
This modification works for me but I just run a few test, so it may not
good enough fro generic purpose but can be a start point to solve this
problem. This modification has at least one side effect. If you use
a channel name beginning with digits, it will be interpreted as number
in the attached code.

Regards,

Noboru
